ISO 15118-3:2015规定了直接在电池电动汽车（BEV）或插电式混合动力电动汽车（PHEV）之间进行高级通信的物理和数据链路层的要求，称为EV（电动汽车）[ISO-1]，基于有线通信技术和固定充电装置[电动车辆供电设备（EVSE）]，除基本信号外，如[IEC-1]中所定义。 它涵盖了参与电能交换的所有参与者之间的总体信息交换。ISO 15118（所有部分）适用于手动连接的导电充电。 ISO 15118的本部分仅涵盖“[IEC-1]模式3和4”电动车辆供电设备以及高级通信模块。

ISO 15118-3:2015 specifies the requirements of the physical and data link layer for a high-level communication, directly between battery electric vehicles (BEV) or plug-in hybrid electric vehicles (PHEV), termed as EV (electric vehicle) [ISO-1], based on a wired communication technology and the fixed electrical charging installation [Electric Vehicle Supply Equipment (EVSE)] used in addition to the basic signalling, as defined in [IEC-1]. It covers the overall information exchange between all actors involved in the electrical energy exchange. ISO 15118 (all parts) is applicable for manually connected conductive charging. Only "[IEC-1] modes 3 and 4" EVSEs, with a high-level communication module, are covered by this part of ISO 15118.
